Description

本発明は、航空機などの乗物用の環境調和システムに関する。   The present invention relates to an environmental harmony system for a vehicle such as an aircraft.

飛行中、航空機は、調和空気をタービンエンジンの圧縮機から得ている。抽気は、圧縮機から高温で出力され、熱交換器を通流して低温になる。この空気は、最終的に客室に供給される。このような圧縮機からの空気の調和プロセスは、エアサイクルとして周知である。   During flight, the aircraft obtains conditioned air from the compressor of the turbine engine. The bleed air is output from the compressor at a high temperature and flows through the heat exchanger to a low temperature. This air is finally supplied to the cabin. This process of conditioning the air from the compressor is known as the air cycle.

しかし、この空気調和方法は、空気を調和するために要する以上のエネルギーが使用されるため効率的ではない。これは、圧縮機によってもたらされる圧力が、大部分の運転点において適切な調和に要求される圧力を超えるためである。このように不必要な圧力を生じさせることは、出力の非効率的な使用につながる。環境調和システムを非効率的に使用することにより、必要以上の燃料が航空機によって消費されるため望ましくない。   However, this air conditioning method is not efficient because it uses more energy than is necessary to harmonize the air. This is because the pressure provided by the compressor exceeds the pressure required for proper harmony at most operating points. Creating unnecessary pressure in this way leads to inefficient use of the output. Inefficient use of environmentally conscious systems is undesirable because more fuel is consumed by the aircraft.

したがって、航空機に使用されるより効率的な環境調和システムが必要とされている。   Therefore, there is a need for a more efficient environmental harmonization system used for aircraft.

環境調和システムは、空気流路内の空気を圧縮する圧縮機を有する。圧縮機はタービンに連結されており、タービンによって駆動される。圧縮機は、空気流路を介して蒸発器と連通している。蒸発器は、圧縮機からの空気を冷却するように構成されている。   The environmental harmony system has a compressor which compresses air in an air channel. The compressor is connected to and driven by the turbine. The compressor is in communication with the evaporator via an air flow path. The evaporator is configured to cool the air from the compressor.

当業者であれば、以下に記載する、発明を実施するための形態から本発明の種々の特徴および利点を理解されるであろう。発明を実施するための形態に伴う図面について以下に簡単に説明する。   Those skilled in the art will appreciate various features and advantages of the invention from the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings that accompany the detailed description are briefly described below.

圧縮機、タービンおよび蒸発器を含む本発明の環境調和システムの概略図。1 is a schematic diagram of an environmental harmony system of the present invention including a compressor, a turbine and an evaporator. 図１のシステムに付加的な蒸発器を加えた環境調和システムの概略図。The schematic of the environmental harmony system which added the additional evaporator to the system of FIG.

図１を参照すると、航空機などの乗り物用の環境調和システム１０が概略的に示されている。図示するように、空気は、空気供給源５８から空気流路１８を通って、客室５４に使用するために調和される。空気流路１８には、圧縮機１１、熱交換器３０、再熱器３８、蒸発器２６、水分除去器３４およびタービン２２が接続されている。圧縮機１１は、シャフト１２によってタービン２２に接続されている。圧縮機１１は、タービン２２により駆動され、モータ４２から動力を受ける。   Referring to FIG. 1, an environmental harmony system 10 for a vehicle such as an aircraft is schematically shown. As shown, the air is conditioned for use in the cabin 54 from the air supply 58 through the air flow path 18. The compressor 11, the heat exchanger 30, the reheater 38, the evaporator 26, the moisture remover 34, and the turbine 22 are connected to the air flow path 18. The compressor 11 is connected to the turbine 22 by a shaft 12. The compressor 11 is driven by the turbine 22 and receives power from the motor 42.

外部空気供給源や他の圧縮機（図示せず）からの抽気など空気供給源５８からの空気は、圧縮機１１へと供給される。圧縮機１１は空気を圧縮し、したがって、空気流路１８内の空気を加熱して、この空気を熱交換器３０へと送る。熱交換器３０は、ヒートシンクへと廃熱して、圧縮機１１からの空気の温度を低下させる。熱交換器３０は、１つまたは複数の熱交換器から構成されてもよい。ヒートシンクは、周囲空気によって冷却されてもよい。次いで、空気は、熱交換器３０から再熱器３８に送られ、その後、第１の蒸発器２６へと送られる。第１の蒸発器２６からの空気は、再熱器３８のヒートシンクとして作用し、これにより、蒸発器２６に要求される伝熱が低下する。   Air from the air supply source 58 such as bleed air from an external air supply source or another compressor (not shown) is supplied to the compressor 11. The compressor 11 compresses air, thus heating the air in the air flow path 18 and sending this air to the heat exchanger 30. The heat exchanger 30 wastes heat to the heat sink and lowers the temperature of the air from the compressor 11. The heat exchanger 30 may be composed of one or more heat exchangers. The heat sink may be cooled by ambient air. The air is then sent from the heat exchanger 30 to the reheater 38 and then to the first evaporator 26. The air from the first evaporator 26 acts as a heat sink for the reheater 38, which reduces the heat transfer required for the evaporator 26.

第１の蒸発器２６において、空気流路１８内の空気の温度は、効果的に著しく低下する。第１の蒸発器２６は、冷媒を伴うベーパサイクル型の蒸発器（ｖａｐｏｒ ｃｙｃｌｅ ｅｖａｐｏｒａｔｏｒ）である。冷媒圧縮機および凝縮器（図示せず）により、第１の蒸発器２６に冷媒ガスが供給され、周知のように第１の蒸発器２６が冷却される。第１の蒸発器２６は、空気流路１８内の空気を冷却し、その結果、空気内の蒸気が凝縮される。この蒸気は、次いで、水分除去器３４によって除去される。その後、空気は、再熱器３８を通って再加熱される。次いで、タービン２２は、空気流路１８に通して空気を客室５４へと流すとともに、空気を膨張させて、さらに空気の温度および圧力を低下させる。   In the first evaporator 26, the temperature of the air in the air flow path 18 is effectively significantly reduced. The first evaporator 26 is a vapor cycle evaporator with a refrigerant. Refrigerant gas is supplied to the first evaporator 26 by a refrigerant compressor and a condenser (not shown), and the first evaporator 26 is cooled as is well known. The 1st evaporator 26 cools the air in the air flow path 18, As a result, the vapor | steam in air is condensed. This vapor is then removed by the moisture remover 34. The air is then reheated through a reheater 38. The turbine 22 then passes the air through the air flow path 18 to the cabin 54 and expands the air to further reduce the temperature and pressure of the air.

タービン２２は、タービンエンジンの圧縮機（図示せず）の抽気から動力を受ける。モータ４２は、シャフト１２に接続されており、タービンエンジンからの抽気の圧力が十分でない場合に圧縮機１１およびタービン２２に付加的な動力を供給する。モータ４２は、制御ユニット４６によって制御される。制御ユニット４６は、シャフト１２の回転速度を制御するように機能し、したがって、圧縮機１１およびタービン２２の回転速度を制御する。このように、客室５４に供給される空気量が制御される。   Turbine 22 receives power from the bleed of a turbine engine compressor (not shown). The motor 42 is connected to the shaft 12 and supplies additional power to the compressor 11 and the turbine 22 when the pressure of the bleed air from the turbine engine is not sufficient. The motor 42 is controlled by the control unit 46. The control unit 46 functions to control the rotational speed of the shaft 12 and thus controls the rotational speed of the compressor 11 and the turbine 22. In this way, the amount of air supplied to the cabin 54 is controlled.

モータ４２、したがって、圧縮機１１およびタービン２２の速度が増すと、客室５４への空気流が増加し、モータの速度が減少すると、客室５４への空気流が減少する。圧縮機１１およびタービン２２に対する利用可能な余剰な出力がある場合には、この付加的な出力を熱交換器３０のラム空気ヒートシンクを駆動させるために使用してもよい。   Increasing the speed of the motor 42 and thus the compressor 11 and the turbine 22 increases the air flow to the passenger compartment 54, and decreasing the motor speed decreases the air flow to the passenger compartment 54. This additional output may be used to drive the ram air heat sink of the heat exchanger 30 if there is excess power available to the compressor 11 and the turbine 22.

この設計の結果、多くのエネルギーを消費することなく第１の蒸発器２６によって多くの熱が除去されるため、客室５４への空気を調和するのに要する出力が最適化される。熱交換器とともに蒸発器を用いることにより、エアサイクルによる調和とベーパサイクルによる調和との間に効率的なバランスが実現する。さらに、再熱器３８および第１の蒸発器２６は、所望の供給温度および相対的な湿度で調和空気を供給するように設計される。   As a result of this design, the first evaporator 26 removes a lot of heat without consuming a lot of energy, thus optimizing the output required to harmonize the air to the cabin 54. By using an evaporator with a heat exchanger, an efficient balance is achieved between air cycle harmony and vapor cycle harmony. Furthermore, the reheater 38 and the first evaporator 26 are designed to supply conditioned air at the desired supply temperature and relative humidity.

また、空気供給源の圧力が冷却に最も効果的な場合、空気供給源の圧力を用いてもよく、そうでない場合には、モータ４２からの出力を介して空気供給源の圧力を増加させてもよい。このように、圧縮機１１からの空気を、最大冷却条件を満たすように非設計条件（ｏｆｆ−ｄｅｓｉｇｎ ｃｏｎｄｉｔｉｏｎ）で過度に加圧する必要がない。モータ４２からシャフト１２への出力によって環境調和システム１０を通流する空気の量を制御することができる。   Also, if the pressure of the air supply source is most effective for cooling, the pressure of the air supply source may be used, otherwise, the pressure of the air supply source is increased via the output from the motor 42. Also good. Thus, it is not necessary to excessively pressurize the air from the compressor 11 under non-design conditions so as to satisfy the maximum cooling condition. The amount of air flowing through the environmental harmony system 10 can be controlled by the output from the motor 42 to the shaft 12.

図２を参照すると、環境調和システム１０に加えられた付加的な蒸発器、つまり第２の蒸発器５０が図示されている。第２の蒸発器５０は、冷媒を伴うベーパサイクル型の蒸発器である。図示されているように、第２の蒸発器５０は、客室５４から空気を得ている。第２の蒸発器５０は、別のベーパサイクル蒸発プロセスを介して客室５４からの空気の過度の熱を除去する。このように、客室５４から再循環された空気は、調和され、空気供給源５８からの新鮮な空気と混合され、これにより、新鮮な空気と再循環空気が効果的に組み合わされる。ある割合の新鮮な空気が再循環空気とともに供給されるため、環境調和システム１０が多くのエネルギーを消費することなく、客室５４内に良質な空気が保たれる。   Referring to FIG. 2, an additional evaporator, or second evaporator 50, added to the environmental conditioning system 10 is illustrated. The second evaporator 50 is a vapor cycle type evaporator with a refrigerant. As illustrated, the second evaporator 50 obtains air from the cabin 54. The second evaporator 50 removes excess heat from the air from the cabin 54 through another vapor cycle evaporation process. In this way, the air recirculated from the cabin 54 is conditioned and mixed with the fresh air from the air source 58, thereby effectively combining the fresh and recirculated air. Since a certain proportion of fresh air is supplied together with the recirculated air, the environmentally friendly system 10 does not consume much energy, and good quality air is maintained in the cabin 54.

第２の蒸発器５０に存在する冷媒は、所望のレベルの加熱度に制御される。冷媒は、冷媒流路８６を通って第１の蒸発器２６に供給され、次いで、冷媒圧縮機７０に供給される。この冷媒圧縮機７０は、環境調和システム１０のベーパサイクルの一部である。冷媒圧縮機７０は、第１の蒸発器２６および第２の蒸発器５０のために冷媒を圧縮する。圧縮された冷媒は、次いで、冷媒凝縮器７２、または補助冷却器（ｓｕｂｃｏｏｌｅｒ）に送られ、冷媒凝縮器７２は、第１の蒸発器２６および第２の蒸発器５０の一方に冷媒を戻す。第１のバルブ７８および第２のバルブ８２が配設されており、第１および第２のバルブは、バルブ制御ユニット９０により制御される。バルブ制御ユニット９０は、どの程度の割合で冷媒凝縮器７２を第１の蒸発器２６および第２の蒸発器５０に戻すかを決定する。このようにして、第１の蒸発器２６と第２の蒸発器５０との間の冷却要求がつり合う。第１の蒸発器２６および第２の蒸発器５０が冷媒流路８６に沿って直列に整列しているため、要求される全冷媒流が最小となる。また、第１の蒸発器２６は、通常、より高温の空気に曝されるため、所望であればシステムに実質的な加熱度を加えるように用いてもよい。加熱度は、ベーパサイクル冷媒圧縮機７０の排出温度を上昇させるように利用することができ、より効率的な運転を実現する。   The refrigerant present in the second evaporator 50 is controlled to a desired level of heating. The refrigerant is supplied to the first evaporator 26 through the refrigerant flow path 86 and then supplied to the refrigerant compressor 70. The refrigerant compressor 70 is a part of the vapor cycle of the environmental harmony system 10. The refrigerant compressor 70 compresses the refrigerant for the first evaporator 26 and the second evaporator 50. The compressed refrigerant is then sent to a refrigerant condenser 72 or a subcooler, which returns the refrigerant to one of the first evaporator 26 and the second evaporator 50. A first valve 78 and a second valve 82 are provided, and the first and second valves are controlled by a valve control unit 90. The valve control unit 90 determines the rate at which the refrigerant condenser 72 is returned to the first evaporator 26 and the second evaporator 50. In this way, the cooling requirements between the first evaporator 26 and the second evaporator 50 are balanced. Since the first evaporator 26 and the second evaporator 50 are aligned in series along the refrigerant flow path 86, the total refrigerant flow required is minimized. Also, since the first evaporator 26 is typically exposed to hotter air, it may be used to add a substantial degree of heating to the system if desired. The degree of heating can be used to increase the discharge temperature of the vapor cycle refrigerant compressor 70, thereby realizing more efficient operation.
